Subject: Question/Problem - Connection reset - Ralink RT3290 - HP Split 13 x2

Hopefully I'm at the right place to ask for help with the problem I
have with my Wifi connection:  It stops really really really often.
Sometimes it works for up to
an hour but usually within 10-15 minutes it just stop/reset and then
does it every few minutes... My presumption is that networkmanager is
able of restarting it most of the time until I get tired of it and
end-up restarting my laptop.  Note that the issue is not happening
under win8.1.

Tested using 3.16 & 3.17.

Device:
03:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe
    Subsystem: Hewlett-Packard Company Ralink RT3290LE 802.11bgn 1x1

Getting the following messsages in syslog which I presume may be related:
